(1) Right Circular Cylinder:

Curved surface area = perimeter x height of cylinder i.e.

Area of each of the flat surface, i.e., of ends i.e.

Total surface area
Example:
Find the height of the solid circular cylinder if total surface area is 600 sq.cm and radius is 5cm.
Solution:
Here cm
Total surface area
Or
Or
Or
cm
Example:
A cylinder vessel, without lid, has to be in coated on both its sides. If the radius of its base is m and its height is 1.4m, calculate the cost of tin coating at the rate of Dollar 2.25per 1000 sq.cm.
Solution:
Given that
Radius of the base of cylindrical vessel,
Height,
Area to be tin coated
sq.cm
Now, cost of tin coating per 1000sq.cm = Dollars 2.25
Total cost of tin coating Dollars
